Questions others have asked:

Can an adhesive be applied to the speed bumps ( 2 x 9')to seal to asphalt to prevent water from draining under the speed bump?

Hi Marke,
Thank you for your question. Unfortunately, we do not have any tests or customer feed back using adhesive to prevent water from draining under the speed bump. You may want to test a small section first.

Have a curved curb, would use this upside down to smooth out the bump, any issues with that? Does it come in black? If now, what paint/treatment would adhere to that surface, or can the yellow be sanded off?

Hi Ken,
Thank you for your question. We have never had a customer that we know of turn it upside down. So we're not quite sure how it would perform. The color is yellow and it's made from recycled plastic. Again her we really have no customer feedback that have tried to paint them.
Thank you,
